v 2 Claims.

a positive locking, fastening device, which is designed to secure a molding or other decorative part to a supporting member through an aperture in the supporting member.

Another object of the invention is to form upturned edges on the fastener to securely hold the molding to the fastener by a snapon action.

A. further object of the invention is to provide a stationary arm struck from the fastener which is so positioned as to be inserted through an aperture in a supporting member and 'by lateral movement of the fastener the arm is brought into holding engagement with the underside of the supporting member.

A still further object of the invention is to provide a second arm struck from the fastener that can be bent into the locking position after the fastener has been inserted through an aperture in a supporting member and engage the underside of supporting member at a point opposite to the first mentioned arm. thereby securely Jocking the arms into holding engagement with the underside of the supporting member.

Other objects and advantages oi. the invention will more fully appear from the following description taken in connection with the accompanying drawings, in which:

Fig. '1 illustrates a top plan view of the improved molding fastener;

Fig. 2 illustrates the improved fastener with locking arms inserted through an aperture in a. supporting member, the arms being shown in the unlocked position, and the fastener being shown in side elevation with the supporting memher and the molding in section; and

Fig. 3 is a view corresponding to Fig. 2 but showing the locking arms in locked position.

Referrin to the drawings, it represents a hollow molding or other decorative ornament provided with the usual spaced inwardly turned flanges l2 and it which is to be mounted on an apertured support it. Preparatory to the assem 'bly of the molding to the supporting surface, preformed fasteners it are inserted in the apertures 2!! of the supporting member It. Each v 22 of the fasteners It are inserted through the r fastener is provided with a locking means that is a 2 fastener securely in position. The molding I0 is now pressed over the fastener l8 until it snaps into place. the fastener l8 holding the molding l0 firmly in the desired position.

The fastener I8 is preferably made of malleable' metal, such as cold roll steel, as distinguished from spring steel and comprises a base 22 having two ofits opposite outer edges upturned forming v-shaped projections 22 and 26 over which the spaced inwardly turned flanges l2 and I l of the molding it are pressed until they snap into the locked position.

The middle portion of the base 22 of the fastener I 2, from the center of the base 22 .to the juncture of the base 22 and the upturned edge 26 is struck upwardly at an acute angle relative to the base, to form an arm 28. A portion of its length, arm 28, is bent reversely downward, upon itself parallel to and pressed against the upwardly bent portion and extending past the base 22 of the fastener it. A hooked portion tll is provided at its lower end for frictional engagement with the under side of the supporting memher it. The arm 28 is formed at such an angle to ermit the hooked portion 30 to be inserted through the aperture 26 of the supporting member iii.

From the middle portion or the opposite side of the base 22 of the fastener it from that which the arm 22 is formed a second arm 32 which is struck downwardly for engagement with the edge of the aperture 22 and the underside of the supporting member l6 opposite the hook at to form a positive locking means for cooperation with hook 32.

In the assembly of the device, the arms 22 and apertures 2d of the supporting member it. The arms 32 engage the edges of the apertures 22 and the underside of the supporting member It. the undersides of the bases 22 or the fasteners id resting against the upper surface of the supporting member E6. The arm 28 is then bent perpendicular to the base 22 of the fastener I 8, moving the hook 30 into engagement with the edge of the aperture 20 and the underside of the supporting member I8 opposite that of the arm 32 and forming a positive locking means in cooperation with the arm 32. The hollow molding it is then pressed over the fastener It, the spaced inwardly turned flanges l2 and It of the molding it snap over the V-shaped projections 22 and 26 of the fastener, holding the molding lil firmly in position in relation to the supporting'memher it.

The device has been illustrated in a preferred form of the invention but it will be understood that various changes including the size, shape and arrangement of parts may be made without departing from the spirit of my invention and it is not my intention to limit its scope other than end of said base portion, a portion of said arm being bent reversely downwardly upon itself, the

downward portion of said arm lying parallel to, and pressing against said upwardly extending portion of said arm, said downwardly bent portion of said arm extending beyond the opposite side of said base of said fastener and toward the other end of said base portion for insertion into an aperture in a supporting member, said downwardly extending portion of said arm having a portion bent outwardly at its free end toward the first mentioned end of said base portion, a second arm struck downwardly and outwardly toward the said other end of said base portion'to engage a lower edge of the said aperture in the supporting member, whereby upon insertion of said downwardly extending arm portions in said aperture and engagement of said second arm with a first lower edge thereof said first arm may be- Name Date 1,860,250 Kellogg May 24, 1932 2,137,542 Murphy Nov. 22, 1938 2,166,916 Lombard Jul 18, 1939 2,168,721 Tinnerman Aug. 8, 1939 2,302,585 Stamy Nov. 17, 1942 2,315,211 Kost Mar. 30, 1943 FOREIGN PATENTS Number Country Date 472,532 Great Britain Sept. 24, 1937 bent to engage its outwardly bent end portion with an edge of said aperture opposed to said first lower edge.

2. A malleable sheet metal fastening device comprising a base, a downwardly and outwar 5 extending stationary arm depending from said base, a second arm extending above and below said base, said second arm being Joined to said base by malleable means intermediate the ends of said arm whereby it is adapted to be bent to project its lower portion in a direction opposite to the direction of said first named arm to form a positive locking means.
